Typically, the Click Rate should not exceed 10%. If not, Google will mark your account. For your information, the normal CTR should range between 0.5% – 10%.
3. The location.
Google has a tracking software and technology. They can trace the origin of the traffic to the small town. So, using different computers with different IP addresses does not secure anything. So, don't try to click on your ad from different internet cafe or public. It will kill you.
Most home users do not use a static IP address for your internet connection. In most cases just disconnect and reconnect the internet will give you a new IP Address. But remember, Google has set a cookie on your computer. They can track the cookie sand see if they come from the same computer.

Your website is not indexed in any search engine, not connected with the leading web site, but getting consistent high visitor? How visitors can access your website and clicks on your ad? It will make Google the smell of death.
10. The inducement in the form of writing.
How about "Please click the link below" or "donate to our site by clicking on the ads"? This kind of ways not in line with the Google TOS. Google can use their search engine, or even a human agent (google her) to check your site from time to time.
11. Conversion from advertisers (Advertiser).
If there is a click on your ad from the visitor then we will get revenue. But whether it brings benefits to advertisers? the point is if there are visitors of our website click advertising voluntarily headed to the advertiser's website, and then the visitor taste linger on website advertisers and or perhaps purchasing a product or subscribing to anything on the website of the advertiser, maybe it would be advantageous for advertisers (Advertiser). If not, then you are in trouble. Smart-Pricing hits first, then your AdSense account disabled. Don't be too is attempting to increase the CTR as big as(using the website which is a bit deceiving visitors clearly)
